If we enable HT and don't disable one of the LPs of the main core - that is the core with the main  sim thread - that second LP, perhaps at 20%, means that the other LP at 100% is only around 80%.

Although with HT enabled we gain maybe 6% when we do run two threads one on each LP since those two threads without HT occupy the same LP and the switching time doubles.

So this kills ultimate fps too - HT Enabled No AM reduces fps.

Thanks Steve.

Yeah makes sense. I can confirm that with HT enabled without AM I did see lower FPS on my 1950X. Which is why I ran it without HT and without AM and got the best performance.

On the AMD 2990WX. I'm curious to see how it runs with HT enabled. And to get all 64 threads I calculated my AM # to be  :

[JOBSCHEDULER]
AffinityMask=‭‭4294967292‬

Pretty insane. On my 1950X without HT the number would have been 65535. But I saw no improvement with AM in the CFG on so I left it out.

I'm gonna try the 32 Core HT Enabled AM setting as above with my new CPU in V4 with 30fps limit and FFTF of 0.1 and see how it goes.

So silly question.  Is there a way to limit frames by not using the locked feature in the UI or using vsync?  Is nvidia inspector an option and if so does anyone know if this works with a VR headset?

 

 

I wouldn't mind a logical processor in my PC. In other words.....a processor that does the logical thing at all times so that I don't have to worry about all of this BS

Rob clearly showed that when using either unlimited FPS or low FFTF value, autogen loading is hampered after some time and never recovers. The question is: does this also happen with the tool? Or is the switch to a higher FFTF value at whatever altitude sufficient to recover the autogen loading?

I installed the Dynamic FFTF product last night and did a quick test flight out of LIPZ with FSL A-320 (latest update) ... came up with some settings that seemed to work well ... good performance and no disappearing AG.  BUT, I really need to do more testing as this is subjective ... unfortunately my two other Test PCs are being used for "something else" so I can only test on my main FS PC.

Cheers, Rob.

If this is something that is worry worthy, then life is indeed treating you well 🙂

Rob, I'm getting a hint that something is "brewing" out there?? Now what could that be? 🤐

Remember that you only need enable enough LPs to load the scenario as fast as it can. If you enable more LPs and there's no significant increase in loading speed, you enabled too many.

Good one.

However, I don't see anyone complaining about getting their head around the technicalities of aircraft or flying. So I don't understand those making complaints about understanding technicalities of PCs

Are you going to update your P3D Wiki with your new settings for Com Day and Com Night? Curious to see what your graphic settings are now. Thank you

Sounds good.

So after a brief test I locked 30 fps with the 30 fps limiter and used an eye candy Corporate Jet addon that is notoriously hard on FPS. That FFTF setting really did the trick with the aforementioned 64 thread AM setting. Think I'll stick with this new config as opposed to unlimited, no FFTF or AM.

 

I'll also have to play around with the AM and see how few threads I can get away with and still lock 30 fps.

 

But the thing with these AMD TR chips is they are primarily geared towards multithreading which is where they shine on CPU intensive tasks. On the 2990WX the single threaded performance is comparable to the 18 Core i9 7980XE, Multithreaded more than double the perf. But due to the architecture of the TR chips they split all that work across the cores. Its really 2 Ryzen CPUs fused into one so it may be beneficial to actually leave all the theads enabled on AM for me. On an i7/i9 its a different ball game. As both these top dog CPUs get the job done but get there in different ways.

 

Also I have always wondered is there a particular part of the P3D cfg that is ideal for placing the Job Sceduler header and the solo AM setting for it? I actually placed it this time right after the MAIN section. I have also put it at the very top and bottom of the cfg in the past when using it as well.

It seems to be working really well after that test so I'll just leave it after the MAIN section I guess....

TextureMaxLoad=3

What about this?

I just removed the entry (which should have restored the default value of 6). This didn't modify the patchy autogen in any way but led to more stutter. Wherever I took TextureMaxLoad=3 from, it seems to be of benefit on my system. Others may vary of course.

Lowering AA does nothing essentially on my machine. That indicates I am clearly CPU bound - as I can confirm based on corresponding performance graphs.

Despite, thanks for having a look,

Kind regards, Michael

I'm testing this as well. I don't run nearly the settings that others do (I'm too busy flying the ac) but will add to the discussion when I have something of substance.

I want to make sure I understand something regarding FFTF and the Dynamic Tool which I use. Here’s the question:

Does the Dynamic FFTF tool work if you run Unlimited or must you set a frame limit for it to work?

I recall from previous posts FFTF settings in the config file seem to only work when not running unlimited.

Please advise, thanks in advance!
